    Prusa MK3S clone crash in Y-axxis

    Hi,

    I bought a Prusa MK3S clone from China.

    The calibration works fine, but when a printout is executed it crashes in the y direction.
    The belt tension display is also incorrect.
    My only conclusion must be that the clone uses the "Blurolls" stepper motors which has a need for a higher current setting.
    I tried to recompile the firmware with a higher current setting, but then the calibration fails by saying that the y-axis path is incorrect....

    Prusa help!

    Hi all,

    I am about as green as it gets when it comes to 3D printing.. I just finished assembling my Prusa MK3s and cannot pass selftest. It’s failing on the x axis, only it passes on the xyz calibration? I have adjusted belts, wiring harnesses and greased rods.. nothing has helped. I’m dead in the water here and could really use some guidance. Please help. Thank you.

    New Prusa user printing TPU

    Hi all from New Zealand. I'm learning to use my new MK3S and have been trying to print Flexfill 98A for the last few days. The printer lays down a perfect track to start and prints for about 2 minutes and then the extruder motor starts cogging which I'm assuming is due to a blocked nozzle (it is very difficult to extract!). I have tried many of the suggestions like hotter, colder, slower, new nozzle but it is always the same ending in more or less time. I have tried reducing the tractor gear tension...

    can print ASA?
    Actually I was already evaluating Prusa MK3S + MMU2S, but I had rejected it because I don't know the reliability of the MMU2S system and because it was open. Doing research on the internet I saw that Josef Prusa himself recommends 2 methods to close his printer, one is the self-construction of the closure and the other is to use a photo studio tent, could the photo studio tent work well?

    Hi all

    My name is Johan and I live in Gothenburg Sweden.

    I have a lot of experince in 3D cad design both in Fusion and in Autocad.

    Recently I have also bought both an open build Workbee CNC router 1500x1000 mm and most recently I bought myself a Prusa MK3S clone while visiting China.

    The Prusa clone is the reason to why I entered this forum.

    Introduction

    Hello everyone! I’m a rookie in the 3D printing world and have not been able to print anything as of yet! I just finished building a Prusa I3 Mk3s and cannot get it to calibrate properly on the x axis. When I select the xyz calibration it goes off without a hitch. So only the X axis in self test mode. I have adjusted belts, bearings, and wiring harnesses. I have even greased the rods just in case. I’m at a total loss, can anyone help?
